MARTIN C. SLODERBECK, OF MARION, INDIANA, ASSIGNOB OF ONE-THIRD TO EDWARD E. LEAPLEY AND ONE-THIRD T0 WILLIAM A. LEAPLEY, BOTH OF MARION, INDIANA.

AUTOMATIC DERAILER.

To all whom it may concern.

lie it known that I, MARTIN C. SLODER- BECK, a citizen of the United States, residing at Marion, county of Grant, State of Indiana, have invented a certain new and useful Im vroved Automatic Derailer, of which the foilowing a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in automatic derailcrs and more mrticularly to that class of derailers as shown in my former Patents Nos. 873,622 and 974,715, the object being to improve the general construction of the derailer whereby a device is formed which is exceedin ly strong and durable and one which will have many advantages over devices of this character now in use.

Another object of the invention is to provide a derailer which is capable of being antomatically operated in one direction toether with means for shifting the derailer into either of its adjusted positions and locking the same,

-'A further object of the invention is to im- )I'OVQ the general construction of derailcr block and to provide novel means for mounting the same in order to resist the end thrust caused by the car wheel against the block, together with means for guiding the block in lits movement toward and from the track I!!! Another object is to provide mechanism for operating the derailer having an 0 eratin lever which is ca able of being loc ed in either of its adjnste ositions by locking devices, one of said locking devices having a positive lock and the other a non-positive lock, the non-positive lock being provided with means for throwin the lever toward the positive lock when re eased.

A further object is to provide a derailer which is capable of being operated by a ground throw through the medium of a cable whereby the same can be installed for tramway purposes.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the ap ended claims.

being shown in section; Fig.2 is a transverse vertical section showing the derailer block, in elevation; Fig. 3 is an end view of one of the lever locks showing the same in its different positions in dotted lines; Fig. 4 is a side elevation of the same; Fig. 5 is an end view showing the positive lock; Fig. 6 is an end view of a portion of the non-positive lock; Fig. 7 is a top plan view of the same; Fig. 8 is a section taken on line 88 of Fig. 7; Fig. 9 is an elevation of the operating rod detached; Fig. 10 is a plan View of the bell crank lever; Fig. 11 is an edge view of the same; Fig. 12 is a plan view of the operating ll'lCClltlIllSlll used in connection with a derailer when placed on a tram-way; Fig. 13 is a section through one of the cable guides and housing; Fig. 14 is a transverse section through the same; Fig. 15-is a side elevation, partly in section, of the ground throw; Fig. 16 is a section taken on line 16-16 of Fig. 13: and Fig. 17 is a section taken on line 17-17 of Fig. 15.

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawings, 1 indicates a road bed constructed in the ordinary manner comprising ties 2 u Jon which the track rails 3 are secured in the usual manner. Mounted upon one of the ties 2 is a plate 4 which is secured in position thereon by spikes as clearly shown and said plate preferably extends under the adjacent track rail 3 and is provided with a bifurcated bearing 5 in which is arranged a vertical pin 6 upon which is ivotally mounted a derailing block 7 which is adapted to co-act with the adjacent rail for a )urpose later described. The block 7 is held into engagement with the adjacent rail 3 by a coil spring 8 which surrounds a rod 9 connected to the adjacent rail and is inclosed by a casin 10 for protecting the same from the weat er.

The lateral movement of the block 7 from its fulcrum point is guided by a laterally projecting slotted member 11 through which extends a bolt 12 carried by one of the ties. the movement of said block being limited by the rod 9 and the member 11. By this con struction, the block is free to move away from the adjacent rail against the tension of the 5 ring which allows the flange of the wheel: when traveling in one direction, to force the same out of the way. The derailer is provided with a vertical oblique face and to be guided olf the medium of gears.

nally.

24 carried by 85 whi h is an bolt flange 13 adjacent its free end which extends to a point 14 from which it substantially parallels the edge of the derailer and forms an inclined face 14: by means of 5 which the derailer may be automatically opened when engaged by the flange of a. car wheel. Extending at an angle to the ins clined' face and at the free end of the derailer, is a derailing face 15 which termi- 0 natesin a downwardly curved face 16 which is provided with a lip 16 which normally rests upon the top of the adjacent rail and catches the face of the wheel in order to cause the same to ride of the track. Various forms of operatingunechanism may beemployed in connection with a derailer clearly set forth and in Figs. 1 and 2, I show a lever operating the same through The operating mechanism comprises a housing 17 in which is mounted a shaft 18 provided with a crank 18 carrying an operating rod 19, the free end of which is connected to a longitudiprojecting pin 20 carried-by a laterally projecting lug 2]. of the derailing block 7. The shaft 18 carries a beveled gear 22 which meshes with the beveled gear 23 which, in turn, meshes with the beveled gear the lever shaft 25 upon the free end of which is mounted a lever 26 which is adapted to co-act with a catch 27 and lock 28. The gear 23 is carried by a vertical-post 20 upon the upper end of mounted a signal target SOand a signal lantern 31 which are given a one-half revolution at each operation of the derailer. The operating rod 19, is preferably formed of sections, comprising a central sed- '.tion and end sections, the end section 19 being provided with an elongated slot in which the crank is mounted, said section bemg connected to the main section by tongue d groove portions held interlocked by :1

shown. The opposite end is provided with an angle coupling section w which is con nected to the central section in a similar manner as the other end section. The crank 18 is provided with guide lugs 32 which prevent the operating bar from striking against the sharp corners and said operating bar is held in a central position upon the crank by lugs 33.

The catch lock 27 is provided with a vertical slot or guide-way to receive the operat ing lever 26 which is locked by a pivot latch member 34 having a weighted end and adapted to be engaged by the curved end 36 I upon the derailing that after the lever has and provided with guides 19 as clearly from over the lever, the weight normally havin a tendency to hold the latch member in the position shown. in Fig. 8. The latch being provided with a beveledhea'd allows the same to be forced to one side of the slot when the lever is forced into the I slot and after the same has passed the latch member, the weight returnsthe latch memher to its normal position. Th slot of the, latch member terminates in ante ged cylindrical portion in which a coil spring 38 is arranged, the upward movement of which is. limited by crossbars 39 carried by a plate 40 to which the upper end of the spring is connected and it will be seen that when the lever is forced into locked position, the spring is compressed so that when the treadle 37 is operated to throw the latch from over the lever, the upward movement of the spring will throw the lever 26 upwardly and toward the positive lock 28.

The lock 28 is provided with two compartments to one side of the slot to receive the lever and in one of these compartments a temporary'lock is mounted. and is especially adapted to be used when trains are being switched and comprises a bolt 41 hav ing an oblique edge-42 which travels on an inclined face 43 and is provided with a notch 44 in which extends the rounded end of a weighted lever 45 which normally holds the bolt in an extended positionin the slot. The belt is-providcd with an oblique portionAG adapted to be engaged by the lever when forced into the slot so as to force the bolt out of its path and it will be. seen passed the bolt, the weight will return the bolt to a locked position. The other compartment of the lock 28 is provided with a sliding bolt all which is normally heldin extended position across the slot by a spring 48 and is provided with an oblique portion 49 in order to allow the lever in its downward movement to force the bolt out of its path. The bolt is provided with a notch :30 adapted to receive the hit of a key'5l in order to allow the bolt to be withdrawn from over the lever by turning the key. I also provide means for locking thebolt 4-? without. the ke which comprises a trcadle which carries a dog 53 adapted to co-act with a notch formed in the bolt 4-7 and it will be seen that by raising i its up on the treadle, the dog will be forced into engagement with the locking bolt and by exerting a downward pressure on the treadle, the dog will be drawn from locked position.

In Figs. 12 to 17, I show an operating mechanism especially constructed to be used in connection with a dcrailer. when placed on a tram-way and in these figures, I show a ground throw comprising a. casing 54 having a hinged lid 55 forming the operating lever to which one end of a cable 56 is conport 60 and inclosed by a casing 61.

free end of the cable is connected to one of I nected which passes over a pulley 57 mounted within the casing 5 1 between guide pulleys 58 and 59 mounted in a suitable sup- The the arms of-a crank 62 which is mounted in a suitable bearing 63 of a plate 64 which is fixed upon the end of one of the ties, the other end of the crank arm being provided with spaced oppositely disposed lugs 65 forming a bearing for the slotted end 66 of anoperating rod 67 which is connected tothe derailer, not shown. The'slotted end 66 of the operating rod 67 is provided with a closing block, not shown, and by this construction, the operating rod is allowed free movement within the bearing of the crank arm.

I have provided means for mounting the blocl: and operating the same whereby the derailer can be moved into an operative or inoperative position by simply shiftingtlie lever from the positive to the non-positive lock.

Having described my invention and set forth its merits what I claim and desire to secure by Letters Patent is---:

1. The combination with a derailer, of a mechanism for shifting the same, an oscillating lever for operating said mechanism, a lock and a catch adapted to beengaged b said lever, said catch being provided witi means for throwing the levertoward the lock when released. 4 9

2. In a derailer, the combination with a spl'ingactuated derailing block, of a mechanism for operating saidbloqk', an oscillating lever for operating said niec hanism, a lock arranged in the path of travel of said lever to one side, a catch arranged in the path of travel to the other side, and means carried by ,said catch for throwing the lever into engagement with the lock when released thereby.

3. In a derailer, the combination with a pivoted derailing block, of mechanism for operating said block, an oscillating lever for operating said mechanism, a catch ar-- ranged in the path of travel of said lever and a spring carried by said catch for forcing said oscillating lever upr ardly when released by said catch, v

4. Ina derailer, the combination with a pivoted spring-actuated derailing block, of mechanism for operating said block, a lever for operating said mechanism, a catch arranged in the path of travel of said lever, and a spring adapted to be engaged and compressed by said lever when in locked position, whereby said lever will be thrown upwardly when released.
